Quick water pump install question

[Fishermark]

I am about ready to install the water pump kit in my Alpha 1, gen 1. I seem to remember reading somewhere that the o-ring on the top of the drive shaft is no longer recommended. I manual doesn't say not to install it, nor does the Mercstuff page. Any thoughts? My memory could be slipping.

Well, it's in and works good. I went ahead and put the o ring on.

If there was a groove for the o-ring,use it .If no groove,the o-ring will slide down and do no harm.On GEN 1,it keeps lube on the splines.On GEN2 the splines are in gear oil,in the upper drive.<br /><br />DHP
